Windows Update Bandwidth Sharing | Breaches

Welcome to our new version of

Telemetry details for Windows Update Bandwidth Sharing

Microsoft might use your computer and bandwidth to share their updates with other Windows users. This they call Delivery Optimization. Microsoft described Delivery Optimization with these words:

Windows updates, upgrades, and applications can contain packages with very large files. Downloading and distributing updates can consume quite a bit of network resources on the devices receiving them. You can use Delivery Optimization to reduce bandwidth consumption by sharing the work of downloading these packages among multiple devices in your deployment. Delivery Optimization can accomplish this because it is a self-organizing distributed cache that allows clients to download those packages from alternate sources (such as other peers on the network) in addition to the traditional Internet-based Windows Update servers.
We set this to the useful setting that shares updates within your local file, not allowing to share updates over your Internet connection, to avoid slowdowns and possible additional costs for your bandwidth.
